Here is the situation. 80 Luv was running like crap dogs. Hesitating, bogging down under throttle, almost sounding like missing. Checked plugs and wires, new cap and rotor; no luck. Decided to check timing... WAY OFF!!! Weird thing, timing mark is super inconsistent, hitting a different spot everytime! Moved timing up to what should be correct (6-8*) and the truck will barely run now and is not drivable at all. What the heck is going on? Where do I start? Is this a timing chain slip or some other instant phenomenon; it all got bad in a hurry after a few wicked burnouts one day... PLEASE HELP!

Did the little springs down inside the dist. that control the advance plates come apart? You would find out by removing the dist. from the truck and taking almost totally apart.

I believe rondog is on to something. A quick check is to remove the cap, turn the rotor a bit counterclockwise against spring tension. When you let go the rotor should return positively back to its original position.

Hey i thank everybody for all the help!! i ended up not jumping into the timing chain set up ...looked like more then me and my friend could handle......but i started to look deep in the dist. cap and noticed a frayed wire (condenser??) so looked deeper and noticed that my points were hitting lower then it was supposed to ...it ended up busting through on one side and really not doing anything sooooo .......i took back the $68 timing chain set up and bought $20 points and condenser....put that in and set the gap to 16-17...then tunned carb. put in new anti freeze (had it) then checked timing...timing still jumps around but now its w/ in specs...it jumps between 8* and 12*........longer story cut shorter, it runs ......and it runs a little better then it ever had since i have had it...(plus the new clutch helped)......hahah NasTY
